6:20 a.m. update: Busy on 494 in west metro

That pesky stall on southbound 494 at 49th Avenue has been there for about 30 minutes. Even though it's on the right shoulder, passing motorists are slowing to take a look. It's packed from I-694 past the scene.

We've also got a stall on the right shoulder of northbound Hwy. 100 at Glenwood Avenue.

The City of Minneapolis will station traffic control agents along Hennepin and Lyndale avenues near the Walker Art Center during the Monday afternoon rush hour to help keep intersections open and traffic moving, a city spokeswoman said.

Construction on mainline routes rolls on but the biggest snags may be on local streets leading to parties, festivals and sporting events across the Twin Cities. Meanwhile light-rail trains won't roll in downtown Minneapolis.
